I am going to cry

Got in an accident about a month ago. Needed a new radiator new front, new hood, new headlights, everything like that but i was told there was no engine damage. So a month later, tongiht, i go to pick up my car and drive it home. I pull in the garage turn the car off get out and it smells like something is burning almost and smoke is coming from under the hood. I opened the hood and there wasnt a ton of smoke but a decent amount. What is the problem!! I am going to cry i was finally gona get my car back and now look...who knows waht will happen now.
